Roughly chop the lettuces: 1 romaine heart (about 4 cups) , 2 oz baby arugula (roughly ½ cup), and ½ head of small raddiccio lettuce (roughly ½ cup). Toss together in a large bowl.
Quarter 1 cup cherry tomatoes, roughly chop ¾ cup pitted green olives, and dice 2 mini cucumbers. Add all ingredients to the bowl and toss with the lettuce.
Take fresh dill and strip the dill leaves and discard the stems. Roughly chop until fragrant, then add to the bowl and toss everything together. Season with salt and pepper.
Crush 2 cups pita chips, I recommend only adding them to the salad immediately before serving so as not to become soggy.
